FLOOR-HINGE.

Specification of Letters Patent.

Patented Dec. 25, 1906.

To aZZ whom, it may concern.-

Be it known that we, GEORGE LEwls SAR- GENT, of the city of New Haven,and ALBERT A. PAGE, of the town of East Haven, in the county of NewHaven, State of Connecticut,

have invented new and useful Improvements in FloorHinges, of which thefollowing is a full, clear, and exact description, when taken inconnection with the accompanying drawings, which form a part thereof,and in which Figure 1 represents a side elevation of a floor-hingeembodying our invention with a part of the top plate removed; Fig. 2, aplan view of the said floor-hinge; Fig. 3, a central vertical section ofa portion of the same and the door to which the hinge is connected.Figs. 4, 5, and 6 are horizontal sections on lines 4 4, 5 5, and 6 6,respectively, of Fig. 1; Fig. 7, a side elevation in detail of theoperating-spindle; Fig. 8, a similar view of the sleeve to which theouter end of the spring is adapted to be connected, and Fig. 9, asimilar view of the sleeve to which the inner end of the spring isadapted to be connected.

In all figures similar letters of reference represent like parts.

This invention relates to the class of floorhinges known asdouble-acting, which return the door under the tension of the spring toits normal position of rest from either side, and more particularly tothey class intended to be located in the floor and support the door inits movement on a stud or pintle.

The object of the invention is the production of a novel hinge havingvarious improvements, as set forth and claimed hereinafter, among whichare a divided top plate so constructed that a portion may be removedwhile the door is mounted on thepintle to permit the adjustment of thetension of the spring without removing the door, a flat band-springconnected through intermediate sleeves with the pintle, and the peculiarform of this connection by which a particularly efiicient yet simplehinge is produced.

Referring to the drawings for a more particular description, the partsdesignated by the letter A represent a hollow cylindrical case open atits upper end, and aa lateral flange projecting from the top. Bdesignates a cap-plate adapted to close the mouth or opening of thecylindrical case A. The plate B has a circular perforation b, and aroundthe perforation b an upwardly-projecting flange 6 extends part way.Through the perforation I) a spindle C and sleeve D are adapted toproject.

The upper end of the spindle is flattened, as shown more particularly inFigs. 2 and 7, for engagement with a socket-bar E, which fits into amortise or groove in the under side of the door X, where it is firmlysecured by means of plates F. (Indicated in outline in Fig. 3.) Theupper end of the door may be mounted by the insertion of arigidly-secured top pivot into a socket in the door-ja1nb or in anyother suitable manner. The spindle C has a groove or recess 0 extendingpartially around its periphery near its top, (see Figs. 4 and 7,) andnear the bottom is a laterallyprojecting stop or feather c. The bottomof the spindle is adapted to travel on balls G in a circular channel orgroove a in the bottom of the case A.

A sleeve H, loosely mounted on the spindle, is provided with a groove h,extending partially around its interior surface, into which the featheror stop 0 of the spindle C projects. The sleeve H rests upon the upperside of a flange 0 of the spindle and has an exterior notch 7L or othermeans for connection with the inner end of a flat band-spring K. Thesleeve H is also provided with an annular flange 72, projectinglaterally from its lower end and on the under side of which is ashoulder or stud 7L3, adapted to come in contact upon the rotation ofthe sleeve H with a stop a in the bottom of the case A.

A sleeve D, loosely mounted on the upper end of the spindle C, has aprojecting annular Y flange d, from the edge of which is a dependingflange d, adapted to engage the outer end of the band-spring K, as shownmore particu larly in Figs. 5 and 6. The sleeve D is provided with anumber of pin-holes d for an adjusting-pin L, which when inserted in oneof the holes (Z is adapted to project into the groove 0 on the spindleC, Fig. 4, while its other end will come in contact with the ends of theflange 1) of the cap-plate B upon the rotation of the sleeve D.

M designates a cover-plate divided on the central line m into two parts.This plate, as

lower end on the balls G in the channel a of the case A and the sleeve Hmounted on the spindle, with the feather c in the groove in and the stud7& against the stop a The spring K is inserted so that its inner endengages the notch h in the sleeve H. The sleeve D is then mounted withthe depending flange d engaging the outer end of the spring K. Thecap-plate B then closes the case, and the pin L is inserted through oneof the holes (1 in the sleeve D into the groove 0 of the spindle C. Theproper tension of the spring K is obtained by turning the sleeve D inthe direction of the arrow, Figs. 4, 5, and 6, for the inner end of thespring is held stationary, as the lower sleeve H cannot turn in thisdirection because of the engagement between the flange 7L3 and stop aThe tension is preserved when the pin L is placed in the proper hole,for the spring cannot unwind, as the outer end of the pin strikes theedge of the flange b on the cap-plate B. lVhen the parts are thusassembled and the door mounted on the spindle, the device is ready foroperation.

If the door is swung to turn the spindle in the direction of the arrow,Figs. 4, 5, and 6, the inner end of the spring K cannot move, as thesleeve H is held stationary, because of the lug It being in contact withthe stop (L The spindle, however, may partially rotate in the sleeve H,for the feather 0 travels in the groove h, Fig. 6. The spindle rotatingin this direction carries the sleeve D around, because the pin Lprojects through the sleeve D and abuts against the end of the slot 0 inthe spindle C, Fig. 4, so that the tension of the spring is increased,and when the force exerted on the door is removed the spring will returnit to its normal position.

If the door be swung to turn the spindle in the direction opposite tothat indicated by the arrrow, Figs. 4, 5, and 6, the sleeve D (engagingthe outer end of the spring K by the flange (1) will be held stationary,because the pin L, projecting through the sleeve D, strikes the end ofthe flange b on the capplate B. The spindle C is free to move in thesleeve D, as the inner end of the pin L slides in the slot 0 of thespindle. The feather c on the spindle striking against the end of thegroove h in the sleeve H turns the sleeve H (which engages the inner endof the spring K) away from the stop a and increases the tension of-thespring to return the door when released to its normal position.

Having now described our invention, which may vary in its detailswithout departing from' the spirit thereof, what we claim, and desire tosecure by Letters Patent, is-

In a floor-hinge, the combination with a case having a shoulder on theoutside thereof; of a rotary spindle operated by the door, or otherarticle, and having a lateral groove; a spring surrounding said spindle;two sleeves loosely mounted on said spindle and having connection withopposite ends of said spring, one of said sleeves having its movementlimited in one direction by said case and in the other by said spindle,and the other sleeve having a flange with a series of radial holesprojecting above said casing; and a pin adapted to be inserted axiallyinto one ofsaid holes and engage with one end said groove in saidspindle, and with the other end said shoulder on said case,substantially as described.

In witness whereof we have hereunto set our hands on the 25th day ofFebruary, 1903.
